ERROR: bad second index at line [...]

What steps will reproduce the problem?

Loading in a large mesh that was converted from assimp (open asset import lib) 
to .obj produces the following issue:

ERROR: bad second index at line [...]

Looking in the obj file at the given line revealed nothing special to me:

#0 vertex normals

# Mesh 'defaultobject' with 1388088 faces
g defaultobject
usemtl DefaultMaterial
f  1/1/ 2/2/ 3/3/ <<<<<<<<< exporter : ERROR: bad second index
f  4/4/ 5/5/ 6/6/
f  7/7/ 8/8/ 9/9/
f  10/10/ 11/11/ 12/12/

mtl lib file:

(Possible something went wrong with the converting in assimp...)

Ah, the face parser is expecting to find another number, like %d/%d/%d instead 
of %d/%d/
